The pharmacist\u2019s role in wart and verruca management<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Warts and verrucas are common, usually benign skin lesions encountered in pharmacy practice.<\/p>

Pharmacists play a central role in their management through education, expectation management, and evidence-based treatment selection. Equally important is recognizing when specialist assessment is required and ensuring timely referral when appropriate.<\/p>

Understanding warts and verrucas<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Cutaneous warts are caused by infection with the human papillomavirus (HPV). Common warts (verruca vulgaris) typically affect the hands and fingers, while plantar warts develop on the soles of the feet, often at pressure points. Verrucas may be painful when walking and can usually be distinguished from calluses by interruption of normal skin lines and the presence of small thrombosed capillaries (\u201cblack dots\u201d) 1, 2<\/sup>.<\/p>

\u00a0<\/p>

Warts may clear without treatment, but studies in primary care populations show that resolution can take many months or longer, particularly in children and adolescents 3<\/sup>. After infection with HPV, warts may also take several months to appear. The likelihood of contracting the virus can be increased by microtrauma to the skin, which facilitates viral entry. As a result, many patients seek advice or treatment to relieve discomfort and limit spread.<\/p>

First-line management in pharmacy<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

From a pharmacy perspective, management should begin with reassurance and a discussion of available treatment options, taking into account symptoms, patient preference, and safety. For asymptomatic or mildly symptomatic warts, active monitoring may be appropriate, alongside advice on hygiene and self-care.<\/p>

\u00a0<\/p>

When treatment is requested, several over-the-counter options are available in pharmacy practice. These include topical acid-based treatments (e.g., salicylic acid or trichloroacetic acid preparations), which exert a keratolytic effect and progressively remove hyperkeratotic tissue, as well as cryotherapy products, which induce local tissue destruction through rapid freezing. These treatments are available in a range of formulations, including solutions, gels and medicated plasters 4, 5<\/sup>.<\/p>

\u00a0<\/p>

Pharmacists should emphasize the importance of regular application (often daily), protecting surrounding healthy skin, and maintaining treatment for several weeks to months. Adherence is critical, as inconsistent use significantly reduces effectiveness.<\/p>

Over-the-counter cryotherapy can also be considered in pharmacy practice. Treatment response may vary, and pharmacists should advise that repeated applications are often required 5, 6<\/sup>.<\/p>

\u00a0<\/p>

Simple measures, such as gently removing thickened skin before treatment and advising patients not to pick or shave lesions, may help reduce spread and improve treatment effectiveness.<\/p>

L\u2019HPV si sviluppa pi\u00f9 facilmente in ambienti che favoriscono macerazione cutanea e microtraumi della pelle1,5<\/sup>.<\/p>

La trasmissione avviene pi\u00f9 frequentemente tramite:<\/p>

  • esposizione a piedi nudi in aree condivise, come piscine o spogliatoi<\/li>
  • condivisione di asciugamani, calzature o superfici contaminate<\/li>
  • autoinoculazione, dovuta a manipolazione, grattamento o rasatura<\/li><\/ul>

    La presenza di pelle danneggiata o ammorbidita aumenta il rischio di infezione.<\/p>

    \n\t\t\t\t\t\t\t\t\tPharmacy-led treatment is not appropriate in certain situations, and referral should be recommended when there is an increased risk of harm or diagnostic uncertainty. Patients with diabetes, peripheral neuropathy, or peripheral vascular disease are at higher risk of skin injury and delayed healing and should be referred for medical assessment.\n\nReferral is also recommended when1, 2, 7<\/sup>:\n
      \n \t
    • The diagnosis is uncertain (e.g., pigmented, bleeding, or rapidly changing lesions)<\/li>\n \t
    • Warts are painful, infected, or extensive<\/li>\n \t
    • The patient is immunocompromised<\/li>\n \t
    • Lesions persist despite several months of appropriate treatment<\/li>\n \t
    • Painful plantar warts that significantly impair walking may benefit from referral to a general practitioner or podiatrist for further assessment and management.<\/li>\n<\/ul>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
